Electromagnetic sensors for wearable healthcare applications
Wearable electronics technology for healthcare management, personal safety, and consumer products enhancement has the potential to transform our everyday life and improve the quality of living of healthcare patients and athletes. Non-invasive healthcare monitoring of body signal bio-parameters – such as movements, respiration, and temperature – without physical intervention or interaction with the patient is particularly of interest in this project. To date, the widespread adoption of many body wearables is limited due to intrinsic limitations mainly related to the flexible/rigid interface: complex wiring, mechanical/electrical reliability, presence of rigid and bulky batteries and charging circuits, washability. Seamless integration is key for user convenience that will ultimately lead to adoption of the technology in everyday applications. This PhD research project envisages developing a wireless body sensor reader that can detect and estimate human body signals through a passive radio-frequency interrogation process and will be integrated with a sensing antenna. It is expected that this PhD research project will change the conventional approach to wearable healthcare electronics, ultimately leading to novel RF circuit architectures that take advantage of modern System-on-a-Package and System-on-a-Chip technology developments, and it may be a key enabler in lowering healthcare costs, particularly for the elderly.

Downhole Wireless RF Communications
There is an industry desire to create and extend the usage of RF wireless technologies to develop future digital-based oil fields. In particular, this PhD project will assess current evolving aspects of wireless technology to be adapted for providing sub-surface monitoring of Oil and Gas wells. Currently most well measurement communications systems employ permanently installed electrical cables or acoustic technologies.
The intention of this project is to assess and model the physical wellbore architecture and EM environment for the application of wireless RF communications in shallow sub-surface well environments; initially identifying the potential transmission schemes and then developing a wireless RF communications system (early prototype) to prove and validate the novel concept. The prototype, once developed, is patentable and will involve the development of new antennas and RF components as well as the system modeling, design, and implementation. At least two IEEE publications are expected from this research as well as conference publications and travel. This engineering research also has the opportunity to deliver low cost well performance for monitoring well head operational efficacy and crude throughout. Applications are expected for the Global Oil & Gas market sectors. Moreover, this proposed wireless well communications modem system can benefit the Global Oil and Gas industry by reducing the high cost of well interventions ($1 million / well) and can provide a key enabler for deploying low cost well measurement technology in wells and further allow for the introduction of new wireless RF sensor technologies.
In addition to this cost savings, there are significant benefits to production optimization by measuring more wells on a continuous basis. It is expected that this PhD research project, to develop the first RF wireless modem system for wells in the Global Oil and Gas Industry, will change the conventional approach to well measurements and monitoring. This can deliver a cost effective technology solution to enable the monitoring of more wells on a continuous basis. Ultimately this RF communications technology implementation can lead to the lowering of the number of routine well interventions, and, it may be a key enabler to lowering crude costs. In addition, the proposed wireless RF sensor communication system may foster the permanent monitoring of Oil and Gas wells with enhanced efficacy.
